Psalms 55:20-23

As for my companion, he betrayed his friends; he broke his promises. His words are as smooth as butter, but in his heart is war. His words are as soothing as lotion, but underneath are daggers! Give your burdens to the LORD, and he will take care of you. He will not permit the godly to slip and fall. But you, O God, will send the wicked down to the pit of destruction. Murderers and liars will die young, but I am trusting you to save me.
